dm ioctl: structs and parameter strings must not overlap
The NUL terminator for each target parameter string must precede the
following 'struct dm_target_spec'. Otherwise, dm_split_args() might
corrupt this struct. Furthermore, the first 'struct dm_target_spec'
must come after the 'struct dm_ioctl', as if it overlaps too much
dm_split_args() could corrupt the 'struct dm_ioctl'.
